TROY P. BURTON AND SILAS W. FORD, OF DENVER, COLORADO.

DIBIGIBLE Application filed February This invention relates to dirigiblespotlights and has for an important object therei of the provision of adevice of this charac ter which may be very cheaply produced and which,at the same time, has a maximum flexibility or range of adjustment.

A further object of the invention is to produce a device of thischaracter which may be very readily adjusted to vary the angle of thebeam so that it willnot annoy oncoming drivers and may, at the sametime, be concentrated upon a desired portion of the roadway.

A further object of the invention is to provide a device of thischaracter which may be completely reversed in its mounting so that itwill direct its light rearwar'dly thereby permitting the device to beused as a trouble lamp when changing tires at the rear of the machine orperforming some similar operation.

.A still further object of the invention is to provide a device of thischaracter which may be very readily assembled from its mounting so thatit may be employed as a trouble light at any point.

These and other objects we attain by the construction shown in theaccompanying drawings, wherein for the purpose of illustration is showna preferred embodiment of our invention and wherein Figure 1 is a planview of a spotlight mounting constructed in accordance with ourinvention;

Figure 2 is a rear elevation thereof;

Figure 3 is a section on the line 38 of Figure 1;

Figure 4c is an enlarged detail elevation of the inner end of the tubeand the operating hand wheel;

Figure 5 is a section onthe line 5-5 of Figure 4.

Referring now more particularly to the drawings, the numeral indicates asuitable bracket which is adapted to be secured rigidly to'the sidemember 11 of a windshield frame. This member includes spaced arms 13,the ends of which have mounted therein adjusting screws 14. The ends ofthe adjusting screws 14 are rounded and engage in similar roundedsockets 15 formed in the outer wall of a tube 16 intermediate the endsthereof and at a point arranged diametrically opposite to one another.The inner end of the tube 16 is provided with a serrated head 17 and inthe bore of the tube is rotat- SPOTLIGHT.

ably mounted a shaft 18 upon the inner end of which is formed a head 19.

Between the head 19 and the adjacent head 17 of the tube a hand wheel 20is splined upon the shaft 18 and has a serrated face 21 for coactionwith the serrations of the head 17. A spring 22 surrounds the shaft between the head 19 and hand wheel and constantly urges the hand wheelinto engagement with the head so thatthe shaft 18 is normally yieldablyheld against rotation. The outer end of the tube is engaged by a head 23formed upon the shaft 18 and this head has parallel side faces-24cwhich'are engaged by the cars 25 on a lamp casing 26. The head 24: andcars 25 are connected by a bolt 27 having a wing nut 28. This wing nutserves as a means for clamping the lamp casing 26 in angularly adjustedposition with relation to the shaft and as a means for rendering thebolt 27 readily removable so that the lamp casing may be separated fromits support and transported from place to place for use as a troublelight.

In the use of the device, the screws 14 will be adjusted to provide asufficient friction against the tube to hold the same in angularlyadjusted positions to which they may be moved. The horizontal angle ofthe beam of light projected from the lamp casing may be regulated byrotating the hand wheel 20 and the angular adjustment of the beam withrelation to the line of movement of the car may be adjusted by swingingthe tube upon its pivots. Operating means are thus provided for asubstantially universal control of the lamp 26 from the interior of thecar. It will, of course, be noted that by rotating the hand wheel, theposition of the lamp casing may be completely reversed so thatthe beamis rearwardly directed instead of forwardly directed, as illustrated.

The construction hereinbefore set forth being obviously capable of acertain range of change and modification without materially departingfrom the spirit of the invention, we do not limit ourselves to suchspecific structure except ashereinafter claimed.

We claim 1. In a spotlight mounting, a bracket adapted for attachmenttoa suitable support, a tube pivoted intermediate its ends to the bracket.a shaft rotatable in the tube, a lamp casing secured to the outer end ofthe shaft, the inner end of the shaft having a head, a hand wheelsplined to the shaft and the adjacent end of the tube, means con stantlyurging the hand Wheel against the stantly urging the hand wheel againstthe inner end of the tube and coacting clutch faces upon the hand wheeland the tube, the lamp casing being angularly adjustable upon the outerend of the shaft.

3. In a spotlight mounting, adapted for attachment to a suitablesupport, a tube pivoted intermed ate its ends to the bracket, a shaftrotatable in the tube, a lamp casin secured to the outer end of theshaft, the inner end of the shaft having; a head, a hand wheel splined'to the shaft and the adjacent end of the tube, means constantly urgingthe hand wheel against the inner end of the tube, coacting clutch facesupon the hand wheel and the tube and a connection between the lampcasing and the outer end of the shaft whereby the lamp casing may bereadily removed therefrom.

a bracket 4. In a spotlight mounting for vehicles, a bracket adapted tobe secured to the Windshield frameof a vehicle and having spaced arms,pivot elements adjustable through said arms, a tube having socketsintermediate its ends in which the pivot elements engage, a shaftrotatable in the tube and having a lamp casing secured to its outer endand means at the'inner euel of the shaft whereby the shaft may berotated and held in ad justed positions with relation to the tube.

5. In a spotlight mounting for vehicles, a bracket adapted to besecuredjto the windshield frame of a vehicle and having spaced arms,pivot elements adjustable through said arn1s,a tube having socketsintermediate its ends in which the pivot elements engage, a shaftrotatable in the tube and having a lamp casing secured to its outer end,means at the inner end of the shaftwhereby the shaft may be rotated andheld in adjusted positions with relation to thetube includ ing a handwheel splined to the shaft, the inner end of the shaft having a head, aspring surrounding the shaft between the head and hand wheel andcoacting clutch faces upon the hand wheel and the ad acent end of thetube;

In testimony whereof we hereunto affix
